Abstract:
The experiment was conducted using thirty-seven desi chickpea genotypes. Observations on quantitative traits had been noted on five plants which were chosen from every plot and replications at different growth stages. Variance analysis relates to observable variations for any trait in individuals. The mean sum of squares due to genotypes studied for all the yield characters reveal that the seed yield and its component traits seem to have considerable genetic variability which can be utilized in selection. Out of 37 genotypes studied, two genotypes namely, RKG 21-4 and PBC 626 showed extra early flowering (<40 Days) whereas, five genotypes viz., BG 4032; RSGD-984; BG 372 (ch); RKG 21-3 and RKG 21-4 recorded early maturity (<90 days) in late sown condition under rice based cropping system; genotypes, GNG-2555; BRC-8; NBeG 1634; GL18148 and IPC 2017-373 possessed height of first pod i.e., more than 30 cm. Twenty genotypes had very small hundred seed weight (< 25g), 15 genotypes had small hundred seed weight (20-25 g), and two genotypes had medium hundred seed weight (26-35 g). For high seed yield per plant, entries RVG 203 (ch); IPC 2006-77 (ch); Phule G 1314-3-27 and NDG 17-6-3 possessed high yield under rice based cropping system. PCV values are higher than GCV values which showed that there is variability among genotypes. High magnitude of PCV coupled with GCV was exhibited by secondary branches, pods per plant, harvest index and plot yield in grams. Days to flowering and plant height were the two traits which showed along high heritability with high genetic advance. Plot yield in grams showed significant and positive association with seed yield per plant, harvest index and pods per plant both at phenotypic and genotypic level. Biological yield, harvest index and pods per plant exhibited positive direct effect on seed yield per plant.
